IMPRO'IVED'APPARATUS FOR HEATING PUDDLINnl-G-F'URNACES.

The Schedule referred to in these Letters Patent and making part of the same.

'To all whom it may concern Be it known that we, SAMUEL A. HILL and CHARLES F. THIIMM, both of Oil City, in the county of Venango, and State of Pennsylvania, have in vented a new and useful Improvement in Apparatus for Generating Heat inPuddling and other Furnaces; and we do hereby declare that the following is a full,

`clear, and exact description thereof, reference being had to the accolnpanying drawings, and to the letters of reference marked thereon.

The nature of our invention consists in the use of the apparatus hereinafter described, for mixing and combining with air or steam, or a-ir and steam combined, a Vapor 0r gas evolved from a liquid or solid that is susceptible of being transmuted into a vapor or gas, which will, when combined with air or steam, or air and steam combined, form an inflammable admixture of vaporous or ga-tseousmatter, that may be burned in a furnace, as a substitutev for fuel.

To enable others skilled in the art to make and use our invention, we will proceed to describe its construct-ion and operation.

In the accompanying drawings, which form part of our specification- I Figure l, Sheet A, is a vertical and longitudinal section of our improvement for generating heat in puddling and other furnaces.

Figure 2, Sheet A, is a side elevation of a puddling-l furnace, and represents our improvement attached to it, and also represents the furnace used for evolving gaseous or vaporous matter, for mixing it with air or steam, by means of said apparatus.

' .Figure 3, Sheet B, is a longitudinal section of an ordinarytpu(idling-furnace, and 'our improvement for generating heat in it.

In the accompanying drawings- A represents a puddlng-furuuce, with our improvement in apparatus for geueratingheat att-ached to it, which apparatusV consists of chambers A and B, pipes C and D, and air-inlets c and f.

The pipeD should be attached to a steam-boiler or to a fan or blower, and the pipe C to a furnace, asindicated at B, or to other device which will evolvea liquid or a solid into a vapor or gas.

The chamber A should becoustructed of fire-brick or other refractory material, which will resist the wasting-action of an intense heat.

As the construction of our improvement, andthe v manner of applying it to a furnace, Awill be readily understood by the skilful mechanic, by reference to the accompanying drawings, and from the foregoing description, we will, therefore, 'proceed to describe the operation, which is as follows:

We place wood, coal, or other solid matter which i can be evolvedv into a'gas or vapor, as hereinbefore depipe I), so that a current of steam or compressed air will ilow` through it into chamber B.

This current of air will draw the gas or vapor evolved in the furnace B', through pipe C, into the chamber B, and at the same time cause airtopassv rapidly through the inlets c andf into the chamber B, where 'the whole become thoroughly. mixed and commingled, so as to form one admixture of gaseous or vaporous matter, which passes into chamber A, where it is ignited and burns with vivid combustion, causing intense heat, which will. act most efhciently upon the ironl and other matter placed in the piuldling-furnace The skilful mechanic will readily understand how vapors or gas evolved in a still orother device maybe used and applied by means of our improved appa- 'ratus.

We are aware that gas and-air have been combined and burned in furnaces forgenerating heat, and, therefore, we wish it clearly understood that we do not claim broadly the use of air, gas, or vapor, nor air, gas, vapor, or steaml combined, and used in a furnace, for the purpose of generating heat. v

Having thus described the nature, construction, and operation of our improvement,

Vhat we claim as of our invention, is-

l. An apparatus fbi-burning gaseous fuel or matter, said apparatus consisting of chambers A and B, pipes C and I), and air-inlets e and f, constructed, arranged, and operating substantially as herein described, and for the purpose set forth. y

2. In combination with the above, a gas or exhalat ing-furnace or apparatus, for supplying the chambers A and B with gaseous fuel or matter for burning', as herein described. y 3. Drawing the gaseous fuel or matter from a furnace or other apparatus, and then forcing it into chambers A and'B, through the medium of compressed air, as hereindescribed, and for the purpose set forth.
